Well actually we are little bit late to bring this news to you. Huawei has released Android 4.2.2 Emotion UI 1.6 B906 official firmware for the Chinese version of Ascend Mate. However as you might already know Chinese versions can be installed on the international Ascend Mate MT01-U06 without having any problems. However we strongly urge you not to flash this if you don’t know what you are doing.
This new firmware brings bug fixes to the previous official B905 firmware which is already an excellent ROM for the Ascend Mate. Numbered as V100R001CHNC00B906 this B906 ROM is intended for the China Unicom Ascend Mate MT01-T00. Changelog mentions that B906 includes stability improvements, crash fixes and security fixes compared to the previous B905. You can set the language to English after the installation.
